[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-2 , Figure 4As shown, a drying device for tea production comprises a drying tank body 1; a blower 11 is fixedly connected to one side of the bottom of the drying tank body 1; a heating strip 13 is fixedly connected to the bottom end of the drying tank body 1; a ventilation plate 12 is fixedly connected to the inside of the drying tank body 1; a first servo motor 16 is fixedly connected to the top of the drying tank body 1; a first gear 17 is fixedly connected to the output end of the first servo motor 16; a rotating column 15 is rotatably connected to the inside of the drying tank body 1; a second gear 18 is fixedly connected to the top of the rotating column 15; the first gear 17 is meshed on the outer side of the second gear 18; a stirring strainer 14 is fixedly connected to the outer side of the rotating column 15; an opening and closing door 100 is provided on the outer side of the drying tank body 1 away from the blower 11; a hinge 19 is fixedly connected to one end of the opening and closing door 100; one end of the hinge 19 is fixedly connected to the drying tank body 1; when working, the opening and closing door 100 is first rotated by the hinge 19, and then the raw materials to be dried are placed in multiple groups of ventilation plates 1 2, and then close the opening and closing door 100, at this time, drive the blower 11 to blow air, heat the heating strip 13, heat the air inside the drying tank body 1, and then drive the first servo motor 16 to drive the first gear 17 and the second gear 18 to start rotating, and drive the rotating column 15 to start slowly rotating inside the drying tank body 1. Because the stirring strainer 14 is above the air permeable plate 12, the raw materials placed above the air permeable plate 12 are turned over and flattened. In this step, the tea leaves may be unevenly heated during the drying process due to uneven thickness of the tea leaves when spread out and no turning during drying, resulting in poor drying effect. The tea leaves may be too dry or wet, which not only affects the taste and mouthfeel of the tea leaves, but also may affect the nutritional value. Therefore, the stirring strainer 14 is continuously turned over during the drying process of the tea leaves, so that the drying effect of the tea leaves is better, and the poor drying effect caused by uneven heating is reduced.

[0024] like Figure 1-4As shown, a vacuum cleaner housing 2 is fixedly connected to the top of the drying tank body 1; a fixing rod 21 is fixedly connected to the end of the vacuum cleaner housing 2 away from the drying tank body 1; a fixing column 22 is fixedly connected to the middle of the fixing rod 21; a fan motor 23 is fixedly connected to the end of the fixing column 22 away from the fixing rod 21; a driving rod 24 is fixedly connected to the output end of the fan motor 23; a fan blade 25 is fixedly connected to the middle of the outer side of the driving rod 24; a dustproof plate 26 is fixedly connected to the middle of the inner side of the vacuum cleaner housing 2; the driving rod 24 is rotatably connected to the middle of the dustproof plate 26; a cleaning brush 27 is fixedly connected to the end of the driving rod 24 away from the fan motor 23; a dust collecting box 28 is provided at the bottom of the vacuum cleaner housing 2 near the dustproof plate 26; when working, the fan motor 23 drives the driving rod 24 to start rotating, driving the fan blades 25 to start rotating, generating air The fan blades 25 rotate to allow air to circulate inside the drying tank body 1. The tea dust generated by drying will be blocked by the dustproof plate 26. The driving rod 24 rotates while the cleaning brush 27 starts to rotate to clean the surface of the dustproof plate 26. The impurities dropped by the cleaning will fall into the dust collecting box 28 and then be cleaned uniformly. In this step, air circulation is required inside the drying tank body 1 during the drying process so that the hot air can dry the tea leaves evenly. Tea dust will be generated in the drying process. The tea dust mixed in the tea leaves will affect the quality of the tea leaves. Therefore, the rotation of the fan blades 25 can achieve stable air circulation inside the drying tank body 1, and the tea dust generated in the drying process will enter the dust collecting box 28 with the air, reducing the possibility of tea dust being mixed in the tea leaves and causing the quality of the tea leaves to decline.

[0025] like Figure 1-2 As shown, a shaking block 31 is fixedly connected to the bottom of the drying tank body 1; a rotating shaft 32 is rotatably connected to the bottom of the shaking block 31; a roller 33 is rotatably connected to the outer side of the rotating shaft 32; a base 3 is fixedly connected to the bottom of the roller 33; a telescopic rod 34 is fixedly connected to one side of the top of the base 3; a discharge chute 35 is fixedly connected to the bottom of the drying tank body 1 near the telescopic rod 34; during operation, after the tea leaves are dried, the opening and closing door 100 is opened, and then the driving rod 24 is retracted and extended. At this time, because the shaking block 31, the rotating shaft 32 and the roller 33 are movably connected, the drying tank body 1 can be tilted, and the tea leaves are discharged from the inside of the drying tank body 1 and fall into the inside of the discharge chute 35 for collection. After the tea leaves are dried, they need to be collected. The collection speed layer by layer is very slow, which affects the efficiency. Therefore, by tilting the drying tank body 1, gravity is used to make the tea leaves fall into the inside of the discharge chute 35 and then collect them, thereby improving the working efficiency.

[0026] like Figure 1As shown, the discharge chute 35 is fixedly connected to a connecting block 4 at one end close to the drying tank body 1; a second motor 41 is fixedly connected to one side of the connecting block 4; a knocking block 42 is fixedly connected to the output end of the second motor 41; when working, the second motor 41 starts to drive the knocking block 42 to rotate, so that it continuously knocks on the outside of the drying tank body 1. In this step, when the drying tank body 1 is tilted to collect tea leaves, tea leaves may be collected with residual content. Therefore, the knocking block 42 continuously knocks the drying tank body 1, so that the drying tank body 1 vibrates, reduces tea residue, and increases the efficiency of tea collection.

[0027] like Figure 2 As shown, a ventilation strip 5 is fixedly connected to the inner side of the drying tank body 1; a first air outlet 51 is opened on one side of the ventilation strip 5; a second air outlet 52 is opened on the outer side of the rotating column 15; the hot air generated during operation will flow inside the ventilation strip 5, and then flow out through the first air outlet 51 to dry the sides of each layer of air-permeable plate 12, and will also flow out from the second air outlet 52 through the rotating column 15. In this step, when drying the tea leaves, the hot air mainly flows from bottom to top, so the effect of drying the sides may be slightly lower, so the tea leaves are dried from the sides through the first air outlet 51 and the first air outlet 51 to increase the drying efficiency.

[0028] like Figure 2 As shown, the blower 11 is fixedly connected with a sieve plate 6 at one end close to the drying tank body 1; when working, the blower 11 needs to pass through the sieve plate 6 to blow air into the drying tank body 1. During this step, when drying the tea leaves, some dust may be sucked into the drying tank body 1 by the blower 11, which will affect the quality of the tea leaves. Therefore, the dust is filtered through the sieve plate 6 to reduce the possibility of dust entering the drying tank body 1 and the possibility of reducing the quality of the tea leaves due to dust.

[0029] like Figure 4 As shown, a UV lamp 7 is fixedly connected to the inner top of the drying tank body 1; when the tea leaves are dried during operation, the UV lamp 7 is turned on. Since ultraviolet rays have a bactericidal effect, the UV lamp 7 can be used to sterilize the tea leaves being dried, thereby reducing the possibility of contamination of the tea leaves by some bacteria.

[0030] The working principle is as follows: when passing through, firstly the opening and closing door 100 is rotated by the hinge 19, and then the raw materials to be dried are placed above the multiple groups of air-permeable plates 12, and then the opening and closing door 100 is closed, and at this time, the blower 11 is driven to blow air, and the heating strip 13 is heated to heat the air inside the drying tank body 1, and then the first servo motor 16 is driven to drive the first gear 17 and the second gear 18 to start rotating, and the rotating column 15 is driven to start slowly rotating inside the drying tank body 1. Because the stirring strainer 14 is above the air-permeable plate 12, the raw materials placed above the air-permeable plate 12 are turned over and flattened. In the process of drying tea leaves, this step may cause uneven heating of the tea leaves due to uneven thickness when the tea leaves are spread out and no turning during drying, resulting in poor drying effect. , resulting in the tea leaves being too dry or damp, which not only affects the taste and mouthfeel of the tea leaves, but also may affect the nutritional value. Therefore, the stirring strainer 14 is continuously turned over during the drying process of the tea leaves, so that the drying effect of the tea leaves is better and the poor drying effect caused by uneven heating is reduced. The fan motor 23 drives the driving rod 24 to start rotating, driving the fan blades 25 to start rotating, generating air flow, and circulating air inside the drying tank body 1. The tea dust generated by the drying will be blocked by the dustproof plate 26, and the cleaning brush 27 will be driven to rotate while the driving rod 24 rotates to clean the surface of the dustproof plate 26. The impurities that fall after cleaning will fall into the dust collection box 28 and then be cleaned uniformly. This step is performed during the drying process of the tea leaves. During the drying process, air circulation is required inside the drying tank body 1 so that the hot air can evenly dry the tea leaves. Tea dust will be generated during the drying process. The tea dust mixed in the tea leaves will affect the quality of the tea leaves. Therefore, the rotation of the fan blades 25 can achieve stable circulation of air inside the drying tank body 1, and the tea dust generated during the drying process will enter the dust collection box 28 along with the air, reducing the possibility of tea dust being mixed in the tea leaves and causing the quality of the tea leaves to deteriorate. After the tea leaves are dried, the opening and closing door 100 is opened, and then the driving rod 24 is extended and retracted. At this time, because the shaking block 31 is flexibly connected with the rotating shaft 32 and the roller 33, the drying tank body 1 can be tilted, and the tea leaves are discharged from the drying tank body 1 and fall into the discharge trough 35 to collect the tea leaves. Collection: After the tea leaves are dried, they need to be collected. The speed of collecting layer by layer is very slow, which affects the efficiency. Therefore, by tilting the drying tank body 1, gravity is used to make the tea leaves fall into the discharge chute 35 and then collect them, which improves the working efficiency. The second motor 41 starts to drive the knocking block 42 to rotate, so that it continuously knocks on the outside of the drying tank body 1. In this step, when the drying tank body 1 is tilted to collect the tea leaves, tea leaves may be left behind. Therefore, the knocking block 42 continuously knocks the drying tank body 1, so that the drying tank body 1 vibrates, reduces tea leaves, and increases the efficiency of tea leaves collection. The hot air generated will flow inside the ventilation strip 5, and then flow out through the first air outlet 51.The sides of each layer of the air permeable plate 12 are dried, and at the same time, the hot air will flow out from the second air outlet 52 through the rotating column 15. In this step, when drying the tea leaves, the hot air mainly flows from the bottom to the top, so the effect of drying the side may be slightly lower, so the tea leaves are dried from the side through the first air outlet 51 and the first air outlet 51 to increase the drying efficiency. The blower 11 needs to pass through the sieve plate 6 to blow air into the drying tank body 1. In this step, when drying the tea leaves, some dust may be sucked into the drying tank body 1 by the blower 11, which will affect the quality of the tea leaves. Therefore, it is filtered through the sieve plate 6 to reduce the possibility of dust entering the drying tank body 1 and the possibility of reducing the quality of the tea leaves due to dust. When drying the tea leaves, turn on the ultraviolet light 7. In this step, because ultraviolet rays have a sterilizing effect, the tea leaves being dried can be sterilized by the ultraviolet light 7 to reduce the possibility of contamination of the tea leaves by some bacteria.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
